ar ssa.

To aZZ whom it may concern:

B it known that 1, CHARLES Vv ILLIAM THOMPSON, a citizen of the UnitedStates, residing at Quincy, in the county of Norfolk and State ofMassachusetts, have invented new and useful Improvements in Fruit Jars,Etc, of which the following .is a spccifica tion.

This invention relates to a receptacle, such as a fruit jar, having anupwardly facing pzu7king-ring seat and a cap having a marginal portionformed to clamp a packing-ring against the seat, clamping pressure beingexerted on the cap by toggles, which include inner members hinged toanchoring means on the receptacle, and outer hooked members bearing onthe cap, and adapted to exert downward pressure thereon when the togglesare rendered active.

The chief object of the invention is to provide improved means foroperatively supporting the toggles on the jar in such manner that thetoggles andthe supporting means may be applied to and removed from thejar as a unit.

The invention is embodied in the'impr venients which I will now proceedto describe and claim.

Of the accompanying drawings forming a part of this specification,

Figure 1 is a side elevation of a jar embodying the invention, the capbeing removed.

Figure 2 is a vertical section of the jar shown The body of the ar 12 1spreferably tapering or tumbler shaped, and is provided with an annularupwardly facing seat 13 for a packing-ring 1 1. The body has an enlargedcylindrical peripheral portion 15 below the seat 13, and a downwardlyfacing shoulder 16 below said portion. The cap 17 Specification ofLetters Patent.

has a downwardly facing marginal portion, formed to bear on thepacking-ring, and a groove 18 formed to engage the hooked toggle membershereinafter described.

lhe ar is prov ded with cap-confining toggles including inner members19, having terminal hinge pintle portions 20, and outer members 21hinged at 22 to the inner members and provided with hooks 23, formed toengage the .cap groove 18. i

{in important element of my invention resides in means employed foroperatively supporting the toggles on, the jar, and preferably embodiedas the next described.

25 represents a band, preferably of wire, loosely surrounding the jarbelow the shoulder 16, the function of said band ,being to confine apair of hinge sockets 26 against the body of the Said sockets engage theterminal pintles-20 to formhinge connections between the toggles and thesupporting means, and are provided with eyes 27 embracing'portions ofthe band 25, lower lugs 28 engaging the shoulder 16 to prevent upwarddisplacement of the hinge sockets 26, and upper confining lugs 29,normally engaging the seat 13, to prevent downward displaoementof thehinge sockets Each of said hinge sockets,its eye 27, and lugs 28 and 29,is'preferably formed from an elongated flexible metal'strip bent betweenits ends to form said socket and eye, the end portions of the stripbeing extended to form the lower lug 28 which is relatively short,

and the upper lug 29 which is longer and is providedwith a hook 29* atits upper end. The arrangement as shown by the drawings, andparticularly by Figures 6 and 7 is such that the toggles are adapted tobe rendered active, as shown by Figure 7, and thereby exert downwardPressure on the cap, and inactive, as shown by Figure 6, to release thecap. \Vhen the toggles are inactive, the portions of the band 25,embraced by the eyes 27, spring outward 'sufficiently to hold the, hooks29 in contact with the seat 13. hen the toggles are rendered active thesaid portions of the band and the lower lugs 28 are pressed inward, thelonger lugs 29 being at the same time forced outward or displaced bycontact of their lower portions with the enlarged jar portion 15, sothat their hooks 29 are removed or displaced'from the packing-ring seat13, as shown by Figure 7 this displacement oocurring after the togglemembers 21 are engaged with the cap, so that the supporting action ofthe lugs 29 is no longer required. The displacement of the lugs 29enables the packing-ring 1 1 to contact effectively with the seat 18.

When the toggles are again rendered inactive, the lugs 29 return to theposition shown by Figure 6, the form of the hooks 29 being such thatthey are adapted to enter the crevice between the seat 13 and thepacking-ring.

It will be seen that the toggles and the describedsupporting means maybe removed as a unit from the jar, ,by springing the lugs 29 outward,and allowing the toggles and supporting means to drop, this beingpermitted by the tapering form of the jar body.

The inner toggle member 19 may be an elongated loop of resilient wire,including longitudinal portions and curved resilient necks connectingsaid portions. One of the longitudinal portions forms the terminal hingepintle member 20, the other longitudinal portion forming the pintle 22of the hinge connection 22 between the inner and outer toggle members.The curved form of the necks connecting said longitudinal portionsrenders the member 19 resilient, so that the toggle is variable orconformable to different receptacles and caps, in some of which thedistance between the top of the cap and the shoulderlG may be greater orless than in others.

The pintle portion 22" is preferably of"- set from the plane of thetoggle member 19, as best shown by Figure 3, this arrangement permittingthe said pintle portion to swing inward to the full extent required whenthe toggle is active. The outer pintle member 21 may be either of openwire construction, as shown by Figure 4;, or may be made of sheet metal.In the latter case, an edge view of said member would be as shown byFigure 3.

I claim: a 1. A jar having in combination, aneupwardly "facingpacking-ring seat, a downwardly facing shoulder below said seat, a capformed to compress a packing-ring on said seat, cap confining togglesprovided with terminal hinge pintles, and means for operativelysupporting the toggles on the jar, said means including a band looselysurrounding the jar below said shoulder, hinge sockets engaging the saidterminal pintles, said sockets being provided with eyes embracingportions of the band, lower confining lugs engaging said shouldertoprevent upward displ cement oi the sockets, and upper confining lugsnormally engaging said seat to prevent downward displace ment of thesockets, the arrangement being such that the toggles are adapted to berendered active, and thereby exert downward pressure on the cap, andinactive to release the cap, the said upper lugs being automaticallydisplaceable from the said seat and from a packing-ring thereon by theoperation or? rendering the toggles active.

2. A jar embodying the combination specified by claim 1, the body of thejar being tapered below said shoulder, so that when the said upper lugsare displaced, the said toggles and supporting means may be separated aunit from the jar.

3. A ar embodying the combination specified by claim 1, each of saidhinge sockets and its band-embracing eye and confining lugs being formedfrom an elongated fleX ible metal strip, bent between its end por tionsto form said sockets and eye, its end portions being extended to formthe said lowerlug, which is relatively short, and the said upper lug,which is longer and is adapted to be displaced outward by the portion ofthe jar above said shoulder when the accompanying toggle is renderedinactive.

4;. In a jar having a closing cap, a capconfining toggle composed. of aninner and an outer member, said inner member being formed as anelongated loop of resilient wire, including a longitudinal portion whichforms a terminal hinge pintle, adapted to engage a hinge socket securedto the jar, another longitudinal portion hinged to the outer togglemember, and curved resilient necksconnecting said longitudinal portions,whereby the toggle is rendered variable.

Tn testimony whereof I have aiiiXed'my signature.

CHARLES WILLIAM THOMPSON.
